WATER-LEVEL" riximcaroaf l Application filed Januar 23,1923. 1 Serial No. 614.365.

To all whom it may concern: 1

Be it known that I, JOHN V. DE WALo,:a' citizen of the United States, residing 'at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Water-Level Indicators, of which the following is a specification. 7

My invention relates to water level indicators, more particularly of a type which may be used on a refrigerator to indicate the water level in the drip pan. The object is to provide a device of a simple and novel construction which will indicate when the drip pan is full of water and means for holding the device out of the drip pan when removing it from under the refrigerator.

This object, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference 'beinghad to the accompanying drawings in which- Figure 1 is a front elevation of a refrigerator having my invention applied thereto, 7

Figure 2 a fragmentary enlarged view of the invention as shown in Figure 1 illustrating the same in another position,

Figure 3 is a section on line 3-3 of Figure2, V i 7 Figure 4 a section on line-4.-4 of Figure 2, and r 1 Figure 5 an enlarged fragmentary view of the indicating means illustrating the manner of holding the device out of the drip pan.

Referring to the drawings, 1 is a refrigerator of any usual construction having adrip pan 2 into which the water drips from' the refrigerator drain pipe. An adjustable rock shaft 3 comprises a tube'et rockably mounted in the front board 5 of the refrigerator anda rod6 adjustable lengthwise within the tube and rockably mounted'in an 7 eye bolt 7 screwed intothe bottomof the refrigerator. An arm 8qextends from rod 5 cator 10 has a stud llwhichjfitsintothe tube and is secured thereto by apin 12. A dial 13'is secured to the frontboard of the refrigerator by screws or other suitable means and hasa projectionl lz struck up from thedial. "A markin 15 of any suitable: description is placed on t e dial to indicate I a and a drip pan, of anad ustable rock shaft I the water level in the drip pan. a 1 When the device is in use and the drip pan empty,the indicator will be in the posiandhas a float 9 mounted thereon. An india 1 and a drip pan, of an adjustable 'rock shaft from the drain pipe of therefrigerator, the

the pan is full cause'the indicator to move into the position shown in Figure 2. When removing the full drip pan from under theravens tion shown in Figure -1.

' float will rise with the water level and when I refrigerator to empty it, indicator 10 is 1 pulled outward ,causing the rock shaft to slide lengthwise, until'the indicator is slightly beyond projection 14 after which it is moved to the opposite side of the projection as shown in Figure 5. This action will raise the float out of the water and hold it in a raised position against the projection.

.The drippan is then free'of the float and ready for removal.

While have described my invention as taking a particular form, it will beundere the spirit thereof, and hence I do not'limit myself to the precise construction setforth,

stood that the various parts of my inven but consider that I am at liberty to makesuch changes and alterations as'fairlycome within the scope of the appended claims. 7 I-laving thus described my invention, what I claim as new'and desire to secure by Letters Patent is i 1. The combination with a refrigerator and a drip pan, of an adjustable rock shaft mounted on the refrigerator; an arm on the 7 rock shaft; a float on the arm; means on the in the refrigerator; arod' adjustably mounted in the tube an arm on the rod; a float on rock shaft for indicating the water level in 4 the arm; means on the tube for indicating the water level in the drip pan, and means.

adapted'to engage the indicating means for a holding the float out of the drip pan. v 3. The combination with a refrigerator mounted on the refrigerator; an arm on the rock shaft; a float onthe arm; an indicator} out of the drip 2 pan. f

a'lhecombination with aijrefrigerator mounted on the refrigerator; anarmonthe on the rock shaft; a dial on the refrigerator, and a projection on the dial for holding-the float out of the drip pan. 7

5. The combination with a refrigerator and a drip pan,'of a tube rockably mounted in the refri erator; a rod adjustably mounted in the tu e; an arm on the rod; a float on the arm an indicator secured, to the tube; a dial secured to the refrigerator, and means on the dial adapted to engage the indicator 10 for holding the float out of the drip pan.

r In testimony whereof I have signed my name to this specification in the presence of two subscribin Witnesses.
